Harvey AI Reviews & Product Details

It is very useful for working with legal documents and large amounts of information. I like how quickly it can analyze documents, summarize complex information, and help organize research. It can save a lot of time when reviewing contracts, preparing documents, or looking for specific information. This AI does it in less time, saving me a lot of time and effort and making my work easier. Review collected by and hosted on G2.com.

Well, it can have some errors, so every time you need to review the information because sometimes it changes; the only bad thing is that you need to take some time to make sure the work is the one that you asked for. However, it continues working well and saves you more time than reviewing. Review collected by and hosted on G2.com.

Contract review is where it's earned its keep — I run agreements through it and get flagged clauses and risk points back fast, with little editing needed afterward. It plugs right into Word and Outlook, so it fits into tools I'm already using daily instead of forcing a separate workflow. The interface is clean too, and setup was smooth from day one. The time saved on first-pass review alone has made it worth the cost. Review collected by and hosted on G2.com.

Integrations with Word and Outlook are solid, but that's about where it stops — I'd like to see it connect with our document management system, too. Customization is also somewhat limited; I've wanted to tweak how outputs are structured to match our templates, but there isn't much flexibility there yet. Review collected by and hosted on G2.com.

What I like best about Harvey AI is its ability to help with legal research, document review, and drafting legal content. It makes it easier to find relevant information, summarize lengthy documents, and organize legal work efficiently. The platform can save time on repetitive tasks and help users work more productively. I also appreciate its potential to simplify complex legal information and support better decision-making.

One limitation of Harvey AI is that its responses may sometimes require additional checking to ensure accuracy. Reviewing complex legal documents can still require human judgment and careful attention to detail. I would also like to see clearer explanations of some results and a simpler workflow for new users. Improving accuracy, ease of use, and transparency would make the platform more helpful and efficient. Review collected by and hosted on G2.com.

What I like most is that Harvey is built around legal work product, not open-ended chat. The assistant is genuinely useful for drafting and summarizing, and for asking grounded questions where it provides sources you can open and verify. Vault is the real differentiator on document-heavy matters: you can upload a large set, run structured extraction or cross-document questions, and get review tables or issue-oriented output rather than having to read every file linearly.

That combination changes the economics of first-pass diligence, contract sets, and research memos. The Word/Outlook workflows help it fit into how lawyers already work, and the enterprise security posture—controls and the promise of no training on client data—makes it easier to use on real matters than a consumer LLM. When it’s used well, it feels less like “AI for AI’s sake” and more like a very fast junior associate that still needs partner-level judgment. Review collected by and hosted on G2.com.

The outputs still need attorney review. Nuance, jurisdiction-specific practice, and deal context can be missed or overstated, so verification is non-negotiable. Pricing and procurement feel enterprise-oriented, which is hard to justify for light or occasional use. Onboarding and prompt discipline matter: teams that treat it like a magic search tool tend to get weaker results than teams that define clear workflows and build in quality checks. Deeper two-way DMS habits and template customization also vary by environment, so consistency isn’t always there out of the box. Review collected by and hosted on G2.com.

I use Harvey AI for contract review and analysis, key data extraction, and legal research. I like how fast it can go through complex documents and pull out the important details, saving me a ton of time on contracts. The speed matters when dealing with large documents, helping me find key info quickly. I appreciate how easy it is to interact with Harvey AI and ask follow-up questions. It provides clear, structured insights, making the review process much more efficient. The initial setup was very easy, which I found really convenient. Review collected by and hosted on G2.com.

One area that could be improved is the accuracy and consistency of responses when dealing with highly complex or industry-specific documents. I would also like to see more customization options for different workflows and better integration with tools such as ERP and project management systems. On accuracy, I think Harvey AI could give clearer source references and more context behind its conclusions, especially with complex contracts. Stronger validation mechanisms would also help reduce the risk of missing important clauses. On integration, deeper connections with ERP, document management, and project management platforms would make it a lot more useful. Review collected by and hosted on G2.com.

I mainly use Harvey AI to speed up my research work, drafting, and for contract analysis. It saves huge time for me, especially in research work as it cuts contracts and due diligence. Harvey AI accelerates drafting, saving a lot of time by eliminating manual checking through automating repetitive tasks like summarization. I like the ability to handle a huge amount of documents for analysis without missing accuracy. I love its workflow automation, which allows building custom, automated logic for repeatable tasks like motion drafting. The Vault feature is also really helpful as it can analyze a huge amount of files at once and provide structured tables of key terms and risk flags. The security and confidentiality aspects ensure our firm's data isn't used for any other purposes like model training, giving us confidence for use in sensitive client matters. It fits smoothly with our existing programs like Microsoft Office 365 and OneDrive, which enhances our productivity. Review collected by and hosted on G2.com.

There are some areas where it needs improvement like the user interface. Enhancing it, especially by having a better interactive onboarding tour for associates, would help everyone effectively use its advanced features. Another issue is the latency of the Vault function. Although it can handle a large amount of documents, it takes more time than usual, causing delays in filtering and categorizing. I think having a document management system with direct, two-way smooth syncing with platforms like iManage would be helpful. The user onboarding process is a bit challenging, especially for those new to platforms like this. Review collected by and hosted on G2.com.

Harvey is phenomenal when it comes to analyzing documentation for review, such as major tax plans or corporate governance drafts. The UI is easy to understand and adjust, and it always performs at a very high level. The AI intelligence is always improving as well, making my practice improve too.

AI hallucinations are always an issue to deal with, and Harvey is not exempt. There are times formatting of certain reports can come out a bit odd, but these are minor issues compared to the benefits received. Review collected by and hosted on G2.com.

What I like best about Harvey AI is how intuitive it is to use while still delivering high-quality results. The interface is clean and easy to navigate, so I was able to start using it without spending a lot of time learning the platform. It fit into my existing workflow with minimal effort, and the integrations made it easy to work alongside the tools I already use.

The AI itself does a great job of understanding context rather than simply summarizing information. It pulls out the details that actually matter and helps organize complex documents in a way that saves time without sacrificing quality. Performance has been consistently fast, even with lengthy files, which has noticeably improved my productivity.

Although it's an enterprise-level investment, the return has been worth it because of the time it saves and the efficiency it adds to document review and research. The onboarding process was smooth, and whenever I had questions, support was responsive and knowledgeable. Overall, it's a polished platform that combines a strong user experience with intelligent AI capabilities. Review collected by and hosted on G2.com.

The biggest downside for me was the pricing. It's a great platform, but the cost can be hard to justify, especially if you're a smaller firm or just getting started. I can see the value if you're using it regularly, but the price definitely gave me pause.

Every now and then, I also had to reword a prompt or ask a follow-up question to get exactly what I was looking for. The AI is smart, but it's not perfect and still benefits from a little guidance on more complex requests. Other than that, I'd love to see it continue expanding its integrations to make it even easier to fit into existing workflows. Review collected by and hosted on G2.com.

I like that Harvey AI is a fast way to get information and is kind of like double-checking or analyzing. It helps me do legal research and analyze third-party agreements and contracts, including nondisclosure agreements. I find it to be a trustful service of information. The platform's drafting and research capabilities, along with its assistant for drafting contracts, are valuable to me. I also found the initial setup to be very easy.

I would like to have a trial option at the beginning. The salespeople oversold the tool for my company, and I feel like I was locked into pricing. The license was not very transparent, so customers don't know what to expect in reality. Review collected by and hosted on G2.com.

Harvey AI saves us hours on legal research and contract review with great context accuracy. It handles heavy groundwork like summarizing clauses and drafting memos, letting our team focus on strategy. It feels like having a super-fast junior associate 24/7. Review collected by and hosted on G2.com.

The high cost and steep onboarding process are the main drawbacks. It takes time to train the team to use it effectively, and outputs still require careful attorney verification to catch occasional hallucinated details or missed nuances Review collected by and hosted on G2.com.
